EDDO V. BATES, OF LOWELL, MASSACHUSETTS.

CARDlNG-ENGINE.

SPECIFICATION forming part of Letters Patent No. 612,303, dated October 11, 1898. Application fil d December 18, 1 897. Serial No. 662.441. (No model.)

To aZZ whom it may concern:

Be it known that I, EDDO V. BATES, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Oarding-Engines; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement on my patent of February 19, 1895, No. 534,418; and it consists in providing two plain rolls on the outer sides of the fluted rolls on the carriage which travels back and forth in the front of the machine. The drawing or sliver passes between the fluted rolls onto the feed-aprons and is laid back and forth on said feed-aprons as the carriage travels from side to side of the carding machine or engine andis carried by the aprons to the carding-rolls.

The object of the invention is to prevent the outer edges of the sliver or drawing frombeing caught and entangled between the fluted rolls shown and described in the abovenamed patent, and the plain rolls are to crowd or press the drawings back outof the way of the fluted rolls, so that the sliver will be laid evenly on the narrow aprons and thus prevent them from being drawn into or caught by the fluted rolls and lay it evenly and uniformly on the aprons.

Referring to the drawings forming a part of this specification, and in which like reference-letters indicate corresponding parts in the different views, Figure l is a front elevation of a sufficient portion of the distributingcarriage to show the invention. Fig. 2 is a detail showing the plain rolls and the bracket by which they are supported.

The distributing-carriage, comprising its guide-frame, bottom rail, driving-shaft, endless chain and spockets, bevel-gears, fluted rolls for the drawing or sliver, 850., is the same as shown and described in the Letters Patent referred to and need not here be described in detail. I have found, however,

that as the carriage moves from-side to side and the sliver or drawing is laid on the feedaprons it not infrequently catches or becomes entangled between the fluted rolls, as

' to and depend from a bracket or arm 0.

the sliver as laid on the feed-aprons projects slightly beyond the edge of the rail or plate at the bottom of the carriage. To obviate this objection, I provide two smooth rolls AA, one oneach side or out-side of the fluted rolls. These rolls A A are loosely mounted on vertical shafts B B. The shafts B B are secizred See Fig. 2.) The bracket or arm 0 is provided at both of its ends with enlarged or extended portions 0 0, having therethrough elongated.

apertures C O. To one side of the center thereof is an upwardly-projecting boss D. The boss D has a vertical hole or aperture through it approximately the size of one or the other of the shafts on the ends of which the fluted rolls E E are mounted.

The bracket or arm 0 is held in position by the shaft of one or the other'of the shafts on which the fluted rolls are mounted by passing said shaft through the vertical hole or aperture in the boss D. It is clear that the arm may be secured in position on the one shaft or the other, since the boss D is located at one side of the center of the bracket, and to use it with one or the other of said shafts it is only necessary to reverse it or turn it end for end.

The elongatedapertures O C are for the purpose of adjusting the smooth rolls A A, as will be presently explained.

G is the loweinrailor plate of the frame of the carriage, against which the smooth rolls AA rest when in their normal positions. The rolls are adjusted to rest against the plate, and the elongated or oblong apertures in the ends of the bracket or arm 0 provide for the proper adjustment. The fluted rolls are revolved positively by the mechanism described in my former patent or any equivalent mechanism, and the smooth rolls A A are revolved by frictional contact with the rail or plate G as the distributing-carriage moves back and forth across the feed apron or aprons.

The arm or bracket 0 is made of such configuration as not to interfere with the mechanism comprising the carriage. The fluted rolls are arranged a short distance away from the plate or rail G, while the plain rolls A A are always in contact with said rail.

The short stub-shafts BB are secured or placed on the arm or bracket G by nuts or in any other suitable manner.

The operation of the invention will be readily understood from the foregoing description. As the sliver or drawing passes between the fluted rolls it is laid on the apron as the distributing-carriage travels back and forth, and as one of the plain rolls always moves in front and the other in the rear of the fluted rolls one or the other pushes the drawing back on the apron out of interference with the fluted rolls.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a carding-engine, a traveling distributing-carriage having fluted rolls for feeding the sliver, revoluble plain rolls on each side of the fluted rolls to guide the sliver and pre- Vent it from being caught between the fluted rolls, and a bar for rotating the plain rolls by frictional contact therewith as the carriage travels back and forth, substantially as described.

2. In a carding-engine, a traveling distributing-carriage having fluted rolls for feeding the sliver, plain rolls, an arm or bracket with short shafts carrying said plain rolls, one on each side of the fluted rolls, and a bottom plate or bar against which the plain rolls rest and are adapted to be revolved by frictional contact as the carriage travels back and forth and thus guide the sliver and prevent it being caught between the fluted rolls, substantially as described.

3. In a carding-engine, a traveling distributing-carriage having fluted rolls for feeding the sliver, and plain rolls, adjustably mounted on a bracket or arm having depending stubshafts on each side of the fluted rolls, said plain rolls adapted to be revolved by frictional contact with the bottom plate or bar of the carriage-frame, and said carriage-frame and plate or bar, substantially as described. In testimony whereof I affix my signature in presence of two witnesses.
